- of the springs supportingthe front portion of the automobile body.

The object of the inventlon is to produce a very durable buffer-of the class referred to and one whichis composed of comparatively few and easily assembled parts and capable of ready attachment to the side sills of automobile frames. I

The buffer of 'my invention comprises the forwardly projecting horizontally disposed bufi'er bar and two supporting members therefor to be connected with the side sills of the automobile frame and each consisting preferably of a bracket adapted for ready adjustment to the side sill, a head to be clamped on the buffer bar, two telescopic sleeves or tubes intermediate said head and bracket, a spiral spring inclosed within said sleeves and a long bolt extending longitudinally through said bracket, sleeves and spring and connected at its threaded end to screws or like securingmeans,

said head, said bolt being slidable in said bracket, so as to permit of the yielding action of the spring and effect the yieldable mounting of the buffer bar.

One advantage of my invention is that the telescopic sleeves or tubes inclosing the spring are held in place without the use of l and another advantage of the [invention is that the brackets connecting the butter bar with the side sills may be readily attached to and detached from said sills and adjusted thereon with the use of bolts without injury to or weakening said sills.

The invention will be fully understood from the detailed description hereinafter presented, reference bcinghad to the ac companying drawings, in which:

Figurel is a top view of the forward portion of anautbmobile equipped with a butter 'and 4.

mechanism embodying my invention; Fig. 2 IS a side view, partly broken away and artly in section on the dotted lines 22 of 1* ig. 1, of the same; Fig. 3 is an enlarged longitudinal section through a portion of the same on the dotted line 33 of Fig. 1, and Fig. t is a transverse section throu h the sidesill and securing bracket 0n the otted line 4--4 1 of Fig. 3.

In the drawings, 10 designates the forward portion of an automob e, 11 the front wheels, 12 the forward and downwardly curved end portions f the usual side sills or bars of the automobile frame, 13 the customary semi-elliptic springs pivoted at their forward ends to the outer ends of said bars or sills 12, "and 14 the horizontal buffer bar mounted forwardly of the vehicle by the meansconstituting my invention and supported from the slde sills or bars 12.

The bracket members supporting the butter bar 14 are designated generally by the numeral 15 and these members correspond with each other and each comprisesa main bracket 16 secured to a side sill 12, a head 17 fastened to the bar 14, telescopic sleeves or tubes 18, 19 intermediate the bracket 16 and head 17, a spring 20 confined within said sleeves 0r tubes and a bolt 21 which extends through the bracket'lti, sprin 20 and sleeves 18,19 and has its forward end screwed into an internally threaded hub 22 which forms an integral part'of the head 17. The bracket 16 1s a casting having an upwardly and forward] inclined upper tubular part 23 through which the bolt 21 passes and a lower base portion 2-.t which bears upon the upper surface of the sill 12 and carries a lower parallel leaf 1 which extends below the upper flanged portion of the sill 12 and carries securing bolts 26 by which the bracket 16 may be readily clamped to the sill 12, as may be clearly understood by reference to Figs. 3 The leaf 25 is formed on the base portion of the bracket 16 by the creation in the side thereof of a longitudinal recess 27 of proper depth and curvature to somewhat snugly pass laterally upon the upper flange of the sill 12. The bracket 16 is one integral casting, and hence is entirel durable, and when said bracket is forme with the special base portion24 it' may be very readily secured to the side sill 12 without cutting readily adjusie into the latter or otherwise modifyingit.

The pecial base .portion 24, permits the bracket 16 and arts carried thereby to be d longitudinally along the sill'12 so as to locate the buffer bar 14 1n its most desirable orzefi'ective relation to the.

automobile. Each head 17 is in the form of x a split ring adapted to receive and clamp the'bar 14 and having an internally threaded hub 22to receive the forward end of the bolt 21. clamped upon the bar by means of a -bolt 28.

The sleeve or tube 18 at its forward end snugly fits upon the hub 22 of the head 17 and said sleeve or tube 18 adjacent to the outer end of the hub 22 is creased inwardly to form an annular shoulder 29 which bears against said end of said hub, the formation said shoulder also increasing the strength and durability of said sleeve or tube. sleeve or tube 19 at its forward end fits within the .rear end of the sleeve or tube 18, and at its rear end said tube 19 is formed with the inwardly extending annular shoulder 30 which bears againstthe forward end of the tubular portion 23 of the bracket 16,-

The spring 20 is a coiled spring and its rear end bears against the shoulder 30 formed on the sleeve or tube 19 and at its forward end bears against the shoulder 29 formed on the sleeve or tube 18, and hence said spring operates to preserve the proper relation of the sleeves ortubes 18, 19 to each other and to the head 17 and bracket 16r- The shoulder 30 on the sleeve 19 and the shoulder 29 on the sleeve-18 add to the stren th of said I parts and in addition afi'ord e -'cient bearing surfaces for engagement with" the provide bearing surfaces for the ends of the spring 20. It will be seen that in .the cona struction of the sleeves 18,.19 presented by me, said sleeves are not rigidly fastened to the bracket 16 and head 17, but are merely assembled in: proper relation thereto: and

, held in suchvrelation by the spring'2O after v the application of the bolt 21 to position.

1' bile'or prior to beingap lied thereto as may Thetbufi'er mechanism. of my invention maybe assembled directly onthe automobe desired, and it will e observed that in assembling the several parts of thefmechanismh no tools are required other than wrenches for tightening the bolts 21, 26, 28,

this bei' ga feature of advantage not only in applying the buffer to an automobile, but in removing the same therefrom when that is necessar'. L y l The bu er mechanism of-my invention is composed of few durablereadily assembled I and disassembled parts, and while I doi 'not limit the invention in every respect tothe "special formation of the base portions 24 of the brackets 16, it is of advantage when ap- Each head 17 is adapted to be The bracket, tubes and" spring bracket 16 and hub 22, respectively, and also plying the mechanism to a car whose sidej sills are formed with upper flanges, to con-" str-uct'said base ortions withlthe recesses members therefor secured to the forwar' end of the vehicle and each comprising a a bracket secured to the vehicle, a head secured to the bar, said head and bracket an inclosing a coiled spring, and a bolt extending through said bracket, tubes and springand secured to telescoipic tubes between i said head, said head having a rearwardly 'projecting hub, and the forward one of said tubes at itsforward endreceivingsaid hub and being creased inwardly to bear against the same and afi'ord' a bearin for the forward end of said spring, an the rear one;

of saidtubes being flanged; inwardly at-its rear end to bear against'theforward end of said bracket and aflord-a-bearing for-thev rear endof saids ring. M l- I 2.- An automoblle bufl'er, comprisingv in combination a bufi'er-bar and" sup orting-v members therefor secured to the orward' end of the vehicle and each comprisinga bracket secured to the vehicle, ahead secured to the bar,'telescopic tubes between said-head and bracket, and inclosing a coiled spring, and a bolt extending through said and, secured to said head, said head hav ng a 'rearwardly' projecting hub, and the forwardone of said tubes at its fr d l 4, at end receiving said hub, an t 1e rear 0 c of said tubes being flanged inwardly at: its rear endl-to bear against the 1 of .said bracket and la-fi'ord a 1 forward en bearing for the rear end of said spring.
